Have you ever been doing a thing all your life and it never occurred to you that there was a better way to do it? I was throwing away most of my non-recyclable bathroom trash without realizing that it could be composted. Then, on the other hand, I was composting stuff like weeds and diseased plants thinking they're organic so it's all good. [Yikes!] In case you might find what I learned helpful, I made this infographic and included some links for you to do more research at the bottom.
Happy rotting!
